🤝 Introduction to Self-Billing Invoices

Self-billing is a smart way to simplify invoicing — especially in the UK, where HMRC allows customers to generate invoices on behalf of suppliers. It’s efficient, but it must follow specific rules. If you're considering self-billing or want to make sure you're doing it right, we’re here to help.

📜 HMRC Guidelines Made Simple

To stay compliant with HMRC, both supplier and customer must sign a written agreement that outlines:

  • Who issues the invoices (the customer)

  • What goods or services are covered

  • How VAT is handled

Each invoice must include:

The correct VAT rate

  • Date of supply

  • Description of goods or services

  • Supplier’s VAT number

  • Any other HMRC-required details

✅ Why Self-Billing Works — and What You Need to Do

Self-billing can:

  • Speed up payments for suppliers

  • Simplify accounting for customers

But it’s important to:

  • Follow HMRC rules carefully

  • Keep accurate records

  • Review your agreement regularly
